I am a Newb to this hobby and this forum so please bare with me if you are shaking your head when reading this.  I couldn't get rid of those spikes when I ran the driver test in Vista even after a clean install.  I don't know how or why I tried this next step but it worked and solved my problem.  All I did was switch my power option (control panel--> Power Options) from High Performance to balanced. That was all. I've included the pictures of both tests for reference.

I have seen those piano keys before.  Smiley

In BIOS look for a setting called "Enhanced Halt State"  or "C1E Enable" and turn it off.

You should really install the OS with all the APCI stuff turned off. That will eliminate most of these types of problems.
